Electrophoretic methods were used to examine the degree of genic variation and genetic relatedness in 11 populations representing 6 species and subspecies of the genus Parus in Korea. The average degree of genic variation of 3 subspecies of P. major was =1.2, =24.4% , D=0.042, and G=0.058, whereas the rest of the species showed slightly lower degree of genic variation than P. major. Genetic relatedness between subspecies and species in the genus Parus showed similar to those reported at comparable taxnonomic levels in other birds. But it appears to be considerably less than that of non avian taxa. Genetic relatedness between 3 subspecies of P.major and P. varius varius was closely related(=0.80), whereas between P.palustrius hellmayri and P.ater amurensis was relatively remote (=0.67). The presumed divergent times of P.palustrius hellmayri, P, ater amurensis , and P. varius varius were about 1.8, 1.6, and 1.0million years before present respectively, and 3 subspecies of P. major were recently differentiated about 100 thousands years before present.
